Slipping Anchor? Testing the Vignettes Approach to Identification and Correction of Reporting Heterogeneity.
We propose tests of the two assumptions under which anchoring vignettes identify heterogeneity in reporting of categorical evaluations. Systematic variation in the perceived difference between any two vignette states is sufficient to reject vignette equivalence. Response consistency - the respondent uses the same response scale to evaluate the vignette and herself - is testable given sufficient...
متن کاملMetastasis: Slipping Control
‘‘And now here it was again, now grown, now in its new home.’’ In her book Resilience, Elizabeth Edwards recalls what raced through her mind when she learned that her cancer had come back and had metastasized. After surgery, radiation, and chemotherapy, she thought that the cancer ‘‘had been chased away.’’ How does cancer find a new home and become metastatic? The short answer is simple: it is ...
متن کاملSlipping through the middle
Tugging and pulling in asymmetric cell divisions n asymmetric divisions, the cell alters the normal process that centers the spindle in the mother cell, but how it regulates the timing of spindle movement is unclear. Now, on page 245, Labbé et al. describe a tethering system that resists premature movement of the mitotic spindle during asymmetric cell divisions in C. elegans embryogenesis. It w...
متن کاملSlipping into trance
It has been hypothesized that highly hypnotizable people spontaneously slip into trance when given imaginative suggestions without prior induction of hypnosis. We tested this in two studies. In Study 1, we examined state reports from ten highly suggestible students following the administration of a suggestion for altered colour perception. The suggestion was administered twice, once with and on...
متن کاملStability of Steady Frictional Slipping
Assistant Professor, Department of Theoretical and Applied Mechanics, Cornell University, Ithaca, N.Y. 14850 The shear resistance of slipping surfaces at fixed normal stress is given by r = r( v,state). Here V = slip velocity, dependence on «state" is equivalent to functional dependence with fading memory on prior V(t), and ar( v,state) /iJV>O. We establish linear stability conditions for stead...
